Settings: DualBeam PLUS™ and Side Imaging®:

Beam Select sets which sonar returns from the transducer will be displayed
on the screen. The available beam frequencies are determined by your
Humminbird® model.
DualBeam PLUS™ models (858c, 958c) and Side Imaging® models (898c
SI, 998c SI) allow you to choose 200/83 kHz, 200 kHz, or 83 kHz.
When set to 200/83 kHz, the returns from both beams are blended
by starting with the 83 kHz wide beam return, dimming it, and then
overlaying it with the 200 kHz narrow beam return. The darker 200
kHz narrow beam sonar returns will stand out from the paler 83 kHz
wide beam sonar returns. The Split Sonar View continues to display
the sonar returns from each beam in their respective windows. The
blended information is shown in the Sonar View and the Sonar Zoom
View. The RTS Window™ in the Sonar View will only show the
returns from the 200 kHz narrow beam.
When set to 200 kHz, only the returns from the 200 kHz narrow
beam will be displayed in the Sonar View and the Sonar Zoom View.
The Split Sonar View will continue to display returns from both
beams in their respective windows. The RTS Window™ in the Sonar
View will display the returns from the 200 kHz narrow beam.
